On one of the last pages, he said he was making up for his past wrongdoings?? So I’m thinking he had a bad experience in the past (whether he did something or someone put the blame on him) that made him feel like he had to ‘help’ Soo Hwa, and we’ll have to wait for a future chap to find out...
Is any done gonna question why he's helping him and why he's sucking dick??? Is he in the closet well (both) of them?
